PrecisionTemp RV550 Operating instructions

Brand: PrecisionTemp

Model: RV550

Type: Operating instructions

PrecisionTemp RV550 is a water heater designed to give a continuous flow of hot water for as long as required and maintain a constant water temperature. It is equipped with a temperature adjustment feature that allows you to set the desired water temperature, ensuring a comfortable showering or bathing experience. The RV550 is also capable of producing very hot water, so be cautious to avoid scalding. It is important to note that the heater is dormant until a hot water tap is opened, and the flow rate must be at least 0.5 GPM for the heating process to start.
